SPECIFICATION forming part of Letters Patent No. 347,452, dated August17, 1886.

Application filed January 7, 1886. Serial No. 187,879. (No model.)

aZZ whom ,it may concern:

Be it known that I, ROBERT N. WILLIAMs, a resident of Vest Troy, in thecounty of Albany and State of New York, have invented certain new andusefullmprovements in Bells; and I do hereby declare that the followingis a full, clear, and exact description of the invention, that willenable others skilled in the art to which it appertains to make and usethesame, reference being had to the accom-' panying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in bells, and more particularly tothe hammer employed in connection with a stationary bell or gong, theobject of which is fully set forth in the following description; and itconsists in the novel construction and combination of parts hereinafterdescribed, and pointed out in the claims.

Figure 1 of the drawings is a side elevation. Fig. 2 is a top plan view.Fig.1; is a cross-section taken at the broken line :0 w in.

Fig. 1.

A represents a bell or gong attached to a supporting-frame, B. The framealso supports a lever, O, pivoted thereon at e. The lever hasoppositely-projecting arms (I and b, and a hammer-support, 9; Arm (1serves as a handle for operating the hammer, and may be grasped by thehand of the operator or connected with a pull by a strap or cord. Thearm b serves as a stop to limit the movement of the lever toward thebell to a position short of contact therewith, as that shown by dottedlines in Fig. 1, and is controlled by the wall f, of frame B, againstwhich it strikes before the lever can travel to the bell.

The hammer consists of a ball, preferably of metal, although I do notwish to limit myself to any particular kind of material. The ball issupported in a concavity or socket in the end 9 of the lever 0, openingout toward the bell. I prefer to make thevconcavity like the ball,spherical in form, and its mouth slightly smaller in diameter than theball,

the end of the lever being of metal and cast around the ball. whatlarger than the ball, that the latter may move freely therein, and themouth of the socket should be large enough to permit the ball to beprojected part way out of the socket through its mouth, when in use, asshown by the dotted lines in Fig. 1.

The operation of the bell is very similar to that of bells heretoforeemployed and as follows: A quick pull upon handle (1 toward thehammersupport lifts the support toward the bell until the stop I)strikes wall f, which suddenly arreststhe motion of the lever before itreaches the bell, and in about the position shown by the dotted linesinFig. 1; but the momentum acquired by the ball or causes it to continueon its journey toward the bell until it strikes the latter, expendingits momentum in the force of the blow, whereupon it falls back bygravity into its socket in the leaver, leaving the bell free to ringwith a clear and uninterrupted sound. Instead of the stop I), the levermay be provided with a cross-bar or stop, S, adapted to come in contactwith the bell-frame B, as shown, and stop the lever at the proper point.

I am aware that hammer-heads have been provided with a sliding bolt toslide out of the head to strike the bell and fall back by gravity, butsuch a form of construction is not reliable. Thebolt is liable to adhereto the sides of its support and refuse to act, thereby making itimpossible to produce any sound whatever from the bell; and I do notclaim such a form of construction. By employing a ball fitting looselyin its socket it is always free to act and requires no lubrication, itis impossible to hold the hammer in contact with the bell, and nosprings or retaining pins or catches, which are liable to get out oforder, are employed.

WVhat I claim as new, and. desire to secure by Letters Patent, is

1. Abell-hammer head composed of a spherical shell and a ball looselyinclosed within said shell, said shell having an opening in its sidecontiguous to the bell, slightly smaller in diameter than the diameterof the inclosed The socket should be some-v ball, substantially asdescribed, find for the In testimony whereof I have hereunto, setpurposes set forth. my hund this 5th day of January, 1886.
